` BRUSH.

To all lwhom it may concern.'

Be it known that I, SIMEON DEsMoND PURDY, a citizen of the United States of An'ierica, residing at Fairville, St. John county, New Brunswick, Canada, have invented a certain new and useful Improvement in Brushes, of whichv the following is a specification.

My invention relates to brushes and par ticularly to shaving brushes, the object of my invention being to provide a shaving brush in which are combined the economies and advantages of a one-piece handle, a bunch of brush bristles having its butt set in rubber, an exterior clamping ring surrounding the brush butt, a central core piece, preferably vulcanized into the butt, and a securing nail or screw piercing this core piece and entering the handle to se- Other Y cure the brush bunch to the handle. features of value will also appear from the following description or drawings wherein- Figure 1 is a side elevation of a brush in which my invention is illustratively embodied;

Fig. 2 is a longitudinal section therethrough;

Fig. 8 is a section on the line ,Zi- 3, Fig. 2;

Fig. 4; is a longitudinal section showing the brush bunch detached from the handle; and

Fig. 5 is a longitudinal section' through a modified construction.

Referring to the drawings, the brush A comprises a bunch of bristles, the butt ends of which are held by a plain clamping ring 10 and embedded in vulcanized rubber.k

In V'the center of the brush butt is a core piece 11 of' wood, fiber, rubber, metal, or the like. This core 11 is preferably vulcanized in the butt, although it is possible to mold a hole in the butt on the vulcanization of the latter, and thereafter insert the core 11. The shape of the core may be cylindrical (Fig. 5) but is preferably tapered in order to better grip the brush bristles.

The handle B, which is preferably turned from wood, has a plain, unthreaded socket 12 bored in one end to receive the butt of the brush, and is of such depth that the outer margin of the clamping ring l0 lies sulficiently far below the lip of the socket to per- Speciicaton of Letters Iiatent.

tact with said lip. In order to holdy the brush in the socket, a dipped naill; is of the core ll'into same purpose.

lVhen a securing screw 14 is used instead lof a nail, some means should be provided to prevent the brush fromv rotating inY the socket as the screw is turned down. A construction such as shown in Fig. 5 is suitable for this purpose. A channel 15 is cut in the bottom of the socket 12 to rcceivesome cementitious substance 16 such The clamping ring 10 is so placed on the brush butt or is of such greater width that its inner margin projects beyond the butt and enters the channel 15. It becomes embedded in the resin and prevents the rotation of the brush when the securing screwjis turned down.

The construction of the brush described A, or a screw, peg

renders it a very economical article of manu facture, while at thejlsame time presenting certain structural advantages not heretofore found in brushes of this type.

The constructions shown and described are merely illustrative of what I claim as my invention andare not to be taken as limitative thereof.

I elaimzm A brush comprising a one-piece handle recessed at one end to form a plain butt-re,- ceiving socket, a bunch of bristles having a butt-end set in rubber and fitting within said socket, said buttend being substantially flat and'bearing against the bottom of the socket, a central'core-piece within saidvbutt, a ring surrounding said butt and between which and said core-piece the butt ends of the bristles are confined, such ring being of less width than the depth, of the socket in the handle to permit the bristles to eX- pand into contact with the edge of the socket, `together with means piercing said core-piece and engaging the handle to secure the bristle bunch thereto.

In testimony whereof I have signed my name to this specification.
